My partner has azoospermia and only one testicle as he had the other removed as a child as a result of an undescended testicle. He blood tests are normal so the urolygist expects a blockage. He has to have an exploratory operation in a few months which I think will also involve the removal of any sperm they may find. My partner seems to think they can just remove the blockage and everything will be fine. Has anyone had any experience of this?
